Z10 not charging or turning on! HELP PLEASE

Hi there. I've had my Z10 for over a year now. Today it shut off, and will not start again. I've taken the battery out and put it back in. I've tried charging it and connecting it through USB to my computer. Nothing is happening. If anybody could help, that would be much appreciated

I'd start by leaving it on the charger overnight, to see if that helps. If not, try warranty or insurance to replace or have the device fixed. I've never seen that problem before with any BlackBerry that I have owned, but it sounds like a serious issue. Good luck

When you have put back the battery, can you see the red led turned on?? Further when you charge the device, can you see any display of a large yellow size (outlined) battery charging??? I also think it to be a drained battery issue and the problem is with the charger or the usb connector of the charger... i think it will be better to try either with another battery (may be borrowed from a friend or repair shop) or to plug in the existing battery of yours to some other device.. at least you will be able to filter out your troubleshooting..
